Intrinsic vs laboratory frame description of the deformed nucleus 48Cr

The collective yrast band of the nucleus 48Cr is studied using the spherical shell model and the Hartree-Fock-Bogoliubov (HFB) method. Both approaches produce basically the same axially symmetric intrinsic state up to the---accurately reproduced---observed backbending. Agreement between both calculations extends to most observables. The only significant discrepancy comes from the static moments of inertia and can be attributed to the need of a more refined treatment of pairing correlations in the HFB calculation
